Black screen and caps lock blinking

[TH3B0]

Hi, I ask you if there has ever happened to you some beautiful lights that light up on the caps lock button. I get 5 long white flashes and 3 short white flashes. I tried to search on the hp guide but what I find is only related to the red flashes. Do you know what they mean? Thank you very much, even if it seems to me that I will have to install again in bios using a usb key.
